Gymnocalycium species question!!

[Maria J]

I have recently acquired a gymnocalycium hybopleurum with a field no of B 44.
Having checked on Ralph Martin's site, this brings up G. Bicolour. I have had a look with Google but can't find if one is a synonym of the other!!
Is this in the NCL? Or can someone familiar with Gymnos help please??

Thanks very much!

John Pilbeam's book says B44 = G.bicolor (no "u"!). Also, that the B numbers are Dorothea Muhr collection nos. One learns something every day :-)

NCL refers bicolor to mostii. I can't find hybopluerium mentioned in that book,
although I do recognise the name, but the are only listing their principle synonyms.

According to this web site:
http://uc.privat.t-online.de/
G. hybopleurum is a synonym of G. mazanense.

I hope this helps.Mind you I'm not sure what the NCL says about mazanense!

Thanks everyone; so far it seems that they are in contradiction! (The species & the field number I mean!)
I wonder which applies to my plant!!

Hi Chris,
it refers mazanense to hossei.

I think one thing we can all agree on is that G. hybopleurum and G. bicolor are not the same thing. G. bicolor seems fairly firmly placed in G. mostii. I think the NCL will show G. mazanense referred to something else, perhaps G. hossei. Strange that there is no mention of G. hybopleurum, I thought that was a fairly stable species, although possibly related to G. monvillei which has swept up a bunch of names in the past.

If you have a field collection number, it is certainly worth maintaining that, and probably worth maintaining the name that goes with it even if it isn't the current accepted taxonomical name. The species it is referred to today may change in the future and you'll be stuck if your label just says Gymnocalycium big-lumped-species-name.
